Rural Affairs and Islands Committee

Salmon Farming in Scotland

Meeting date: 5 June 2024

Finlay Carson

One of the statements that you just made illustrated the issue that we have. You quoted the mortality of X million fish, but you did not contextualise that or provide any information about whether that is proportionate or acceptable. We continue to hear that message. We are not sure whether 1.5 million fish dying is reasonable or can be accepted. Understanding the context is one of the issues that the committee has. For example, a 1 per cent mortality, or more than that, in a beef herd might be significant, but a 5 per cent mortality in the aquaculture industry might not be significant compared with other types of farming. With situations like that, does the public get enough information to make educated decisions on whether aquaculture is making progress?

Thank you. That is a good place to start. I move to a question from Ariane Burgess.

Salmon Farming in Scotland

To conclude this section, I want to put it into perspective. As a former farmer, I remember that we used to inject our calves with selenium to give their immunity a little boost. We used to give them an infectious bovine rhinotracheitis injection, or they would get bovine viral diarrhoea, and, on the back of that, there was quite a high use of antibiotics. We were treating conditions that were the result of various infections. Over time, however, the livestock industry has reduced the use of antibiotics quite significantly—for instance, as a prophylactic treatment for dry cows with mastitis. We have seen a dramatic drop in the use of antibiotics in other types of farming and food production. Are we seeing the same progress in aquaculture?

This inquiry and the report that we will be doing are all about progress and whether we are making progress. In agriculture, the advances in the area of inoculations and vaccinations have had the knock-on effect of reducing the use of antibiotics. Are we seeing the right direction of travel in aquaculture? Are we on the right path to reducing the use of antibiotics—not Ivermectin, which is a wormer for cattle, but the one that is used for fish? Are we seeing progress leading to the reduction in the use of these types of chemicals?

We will now hear from our second panel of witnesses, which is made up of aquaculture scientists. I welcome to the meeting Professor Simon MacKenzie, who is head of the institute of aquaculture at the University of Stirling; Professor Sam Martin, who is the director of research in the school of biological sciences at the University of Aberdeen; and Dr Helena Reinardy, who is a lecturer and teaching fellow at the Scottish Association for Marine Science. Joining us remotely are Dr Annette Boerlage, who is a research fellow in aquatic epidemiology in the school of veterinary medicine at Scotland’s Rural College, and Professor Lynne Sneddon, who is the chair in zoophysiology in the department of biology and environmental sciences at the University of Gothenburg.

I am glad that I got my lips around all of that. We have approximately 90 minutes of questions, and I will kick off with a fairly straightforward one.

The Scottish Science Advisory Council’s report on the use of science and evidence in aquaculture concluded that science on aquaculture is “not sufficiently visible”. Do you consider public understanding of the salmon farming industry to be based on reliable information?

Yes.

There is a public perception of aquaculture, and views on it can be quite polarised, as are so many topics these days. Is the public understanding based on accurate and reliable information? The job of the committee in the piece of work that we are doing is to see whether there has been progress in the past five years. It is important that we base our decisions on accurate information. Professor MacKenzie, is the information that the public have reliable and sufficient for them to make up their minds on aquaculture?

We are looking at environmental impacts. If you do not have a question, I have one and then we can move on to the next one.

Who is keen to respond?

Okay—that is helpful.

One of the report’s recommendations was for

“coordination with the data ... and comprehensive overview of all fish health, welfare and treatment issues across the sector”.

Have we made improvements over the past five years to ensure that there is co-ordination of fish health data? Is it better than it was five years ago?

The response to that might be very similar to the response to my question, unfortunately. If nobody feels that they can offer a view on the interaction between wild and farmed salmon, we will leave it there.
